• google changing crawl speed: doesn't seem to work. Why?

  - by Olivier Pons

  I've changed 3 days ago the google crawling speed of mywebsite. Here it is: This means: 2 demands by second. I've got the message on the google webmasters tools that the change speed has been taken in account: But after more than three days, nothing happens: still one request every ten seconds See here: My webserver is very fast and can handle up to twenty simultaneous connexions. And my website is brand new, this means google is almost the only one here crawling my website. After more than 30000 successful requests (= no 404), I think there's something going on... or maybe this is just a bug? Has anyone ever had this problem?

• Fun With the Chrome JavaScript Console and the Pluralsight Website

  - by Steve Michelotti

  Originally posted on: http://geekswithblogs.net/michelotti/archive/2013/07/24/fun-with-the-chrome-javascript-console-and-the-pluralsight-website.aspxI’m currently working on my third course for Pluralsight. Everyone already knows that Scott Allen is a “dominating force” for Pluralsight but I was curious how many courses other authors have published as well. The Pluralsight Authors page - http://pluralsight.com/training/Authors – shows all 146 authors and you can click on any author’s page to see how many (and which) courses they have authored. The problem is: I don’t want to have to click into 146 pages to get a count for each author. With this in mind, I figured I could write a little JavaScript using the Chrome JavaScript console to do some “detective work.” My first step was to figure out how the HTML was structured on this page so I could do some screen-scraping. Right-click the first author - “Inspect Element”. I can see there is a primary <div> with a class of “main” which contains all the authors. Each author is in an <h3> with an <a> tag containing their name and link to their page:     This web page already has jQuery loaded so I can use $ directly from the console. This allows me to just use jQuery to inspect items on the current page. Notice this is a multi-line command. In order to use multiple lines in the console you have to press SHIFT-ENTER to go to the next line:     Now I can see I’m extracting data just fine. At this point I want to follow each URL. Then I want to screen-scrape this next page to see how many courses each author has done. Let’s take a look at the author detail page:       I can see we have a table (with a css class of “course”) that contains rows for each course authored. This means I can get the number of courses pretty easily like this:     Now I can put this all together. Back on the authors page, I want to follow each URL, extract the returned HTML, and grab the count. In the code below, I simply use the jQuery $.get() method to get the author detail page and the “data” variable that is in the callback contains the HTML. A nice feature of jQuery is that I can simply put this HTML string inside of $() and I can use jQuery selectors directly on it in conjunction with the find() method:     Now I’m getting somewhere. I have every Pluralsight author and how many courses each one has authored. But that’s not quite what I’m after – what I want to see are the authors that have the MOST courses in the library. What I’d like to do is to put all of the data in an array and then sort that array descending by number of courses. I can add an item to the array after each author detail page is returned but the catch here is that I can’t perform the sort operation until ALL of the author detail pages have executed. The jQuery $.get() method is naturally an async method so I essentially have 146 async calls and I don’t want to perform my sort action until ALL have completed (side note: don’t run this script too many times or the Pluralsight servers might think your an evil hacker attempting a DoS attack and deny you). My C# brain wants to use a WaitHandle WaitAll() method here but this is JavaScript. I was able to do this by using the jQuery Deferred() object. I create a new deferred object for each request and push it onto a deferred array. After each request is complete, I signal completion by calling the resolve() method. Finally, I use a $.when.apply() method to execute my descending sort operation once all requests are complete. Here is my complete console command: 1: var authorList = [], 2: defList = []; 3: $(".main h3 a").each(function() { 4: var def = $.Deferred(); 5: defList.push(def); 6: var authorName = $(this).text(); 7: var authorUrl = $(this).attr('href'); 8: $.get(authorUrl, function(data) { 9: var courseCount = $(data).find("table.course tbody tr").length; 10: authorList.push({ name: authorName, numberOfCourses: courseCount }); 11: def.resolve(); 12: }); 13: }); 14: $.when.apply($, defList).then(function() { 15: console.log("*Everything* is complete"); 16: var sortedList = authorList.sort(function(obj1, obj2) { 17: return obj2.numberOfCourses - obj1.numberOfCourses; 18: }); 19: for (var i = 0; i < sortedList.length; i++) { 20: console.log(authorList[i]); 21: } 22: });   And here are the results:     WOW! John Sonmez has 44 courses!! And Matt Milner has 29! I guess Scott Allen isn’t the only “dominating force”. I would have assumed Scott Allen was #1 but he comes in as #3 in total course count (of course Scott has 11 courses in the Top 50, and 14 in the Top 100 which is incredible!). Given that I’m in the middle of producing only my third course, I better get to work!

• Ubuntu USB boot failure

  - by Steve

  When trying to boot from a boot USB drive I got the message, "Vesamenu.c32:Not a com32r image." I was trying to boot a fairly new Toshiba laptop with a Ubuntu 10.04.2 LTS created USB boot. I re-created the USB drive with 11.04 and it booted fine. These were both 32 bit versions even though the laptop is a 64 bit. I was trying to create a generic boot USB that would work on everything I might try it on. What is the consensus on this idea? Any solution to the above error? Thanks from a noobe.

• 8 Deadly Commands You Should Never Run on Linux

  - by Chris Hoffman

  Linux’s terminal commands are powerful, and Linux won’t ask you for confirmation if you run a command that won’t break your system. It’s not uncommon to see trolls online recommending new Linux users run these commands as a joke. Learning the commands you shouldn’t run can help protect you from trolls while increasing your understanding of how Linux works. This isn’t an exhaustive guide, and the commands here can be remixed in a variety of ways. Note that many of these commands will only be dangerous if they’re prefixed with sudo on Ubuntu – they won’t work otherwise. On other Linux distributions, most commands must be run as root.

• Superpower Your Touchpad Computer with Scrybe

  - by Matthew Guay

  Are you looking for a way to help your Touchpad computer make you more productive?  Here’s a quick look at Scrybe, a new application from Synaptics that lets you superpower it. Touchpad devices have become increasingly more interesting as they’ve included support for multi-touch gestures.  Scrybe takes it to the next level and lets you use your touchpad as an application launcher.  You can launch any application, website, or complete many common commands on your computer with a simple gesture.  Scrybe works with most modern Synaptics touchpads, which are standard on most laptops and netbooks.  It is optimized for newer multi-touch touchpads, but can also work with standard single-touch touchpads.  It works on Windows 7, Vista, and XP, so chances are it will work with your laptop or netbook. Get Started With Scrybe Head over to the Scrybe website and download the latest version (link below).  You are asked to enter your email address, name, and information about your computer…but you actually only have to enter your email address.  Click Download when finished. Run the installer when it’s download.  It will automatically download the latest Synaptics driver for your touchpad and any other components needed for Scrybe.  Note that the Scrybe installer will ask to install the Yahoo! toolbar, so uncheck this to avoid adding this worthless browser toolbar. Using Scrybe To open an application or website with a gesture, press 3 fingers on your touchpad at once, or if your touchpad doesn’t support multi-touch gestures, then press Ctrl+Alt and press 1 finger on your touchpad.  This will open the Scrype input pane; start drawing a gesture, and you’ll see it on the grey square.  The input pane shows some default gestures you can try. Here we drew an “M”, which opens our default Music player.  As soon as you finish the gesture and lift up your finger, Scrybe will open the application or website you selected. A notification balloon will let you know what gesture was preformed. When you’re entering your gesture, the input pane will show white “ink”.  The “ink” will turn blue if the command is recognized, but will turn red if it isn’t.  If Scrybe doesn’t recognize your command, press 3 fingers and try again. Scrybe Control Panel You can open the Scrybe Control panel to enter or change commands by entering a box-like gesture, or right-clicking the Scrybe icon in your system tray and selecting “Scrybe Control Panel”. Scrybe has many pre-configured gestures that you can preview and even practice. All of the gestures in the Popular tab are preset and cannot be changed.  However, the ones in the favorites tab can be edited.  Select the gesture you wish to edit, and click the gear icon to change it.  Here we changed the email gesture to open Hotmail instead of the default Yahoo Mail. Scrybe can also help you perform many common Windows commands such as Copy and Undo.  Select the Tools tab to see all of these commands.   Scrybe has many settings you may wish to change.  Select the Preferences button in the Control Panel to change these.  Here’s some of the settings we changed. Uncheck “Display a message” to turn off the tooltip notifications when you enter a gesture Uncheck “Show symbol hints” to turn off the sidebar on the input pane Select the search engine you want to open with the Search Gesture.  The default is Yahoo, but you can choose your favorite. Adding a new Scrybe Gesture The default Scrybe options are useful, but the best part is that you can assign gestures to your own programs or websites.  Open the Scrybe control panel, and click the plus sign on the bottom left corner.  Enter a name for your gesture, and then choose if it is for a website or an application. If you want the gesture to open a website, enter the address in the box. Alternately, if you want your gesture to open an application, select Launch Application and then either enter the path to the application, or click the button beside the Launch field and browse to it. Now click the down arrow on the blue box and choose one of the gestures for your application or website. Your new gesture will show up under the Favorites tab in the Scrybe control panel, and you can use it whenever you want from Scrybe, or practice the gesture by selecting the Practice button. Conclusion If you enjoy multi-touch gestures, you may find Scrybe very useful on your laptop or netbook.  Scrybe recognizes gestures fairly easily, even if you don’t enter them perfectly correctly.  Just like pinch-to-zoom and two-finger scroll, Scrybe can quickly become something you miss on other laptops.

• Disable default error pages/error messages in IIS

  - by Antoine

  I have this web application (ASP.Net MVC 3) that on certain conditions returns a custom JSON string with a HTTP status code for an error (403, 415, 500). It is deployed on a Win 2008 R2 server with IIS 7.5 Initially I was gettting the standard HTML pages for the error instead of the JSON data. I removed the error pages for these errors in the app settings. But now my queries which should return some JSON data return a single error line. When the server gives me 403, I have the message "You do not have permission to view this directory or page." (simple line, no HTML around it). What can I do to deactivate this and finally get what the app is returning and not what the server wants to return?

After this operation, 126 MB disk space will be freed. Do you want to continue [Y/n]? Other info: Why do the "iodbc" and "libmyodbc" packages conflict with each other? The root problem is that I need to use a new feature introduced in the latest MySQL Workbench builds (DB Migration) which uses odbc for that matter. Here is what Mysql doc says about it : Linux The Migration Wizard uses iODBC as a driver manager for all of its ODBC connections in Linux. This may give you some troubles because most Linux distributions provide ODBC drivers compiled against unixODBC. This is another driver manager not supported by MySQL Workbench so you won’t be able to use those drivers unless you compile them against iODBC. Here’s what you should do. Make sure that you have iODBC installed. If you are using Debian, Ubuntu or another Debian based distro, type this command in your terminal: $ sudo apt-get install iodbc libiodbc2-dev libpq-dev libssl-dev For RPM based distros (RedHat, Fedora, etc.) type this command instead of the previous one: $ sudo yum install iodbc iodbc-dev libpqxx-devel openssl-devel Now we need to install the PostgreSQL ODBC drivers. Download the psqlODBC source tarball from here. Use the latest version available for download. As of this writing the latest version corresponds to the file psqlodbc-09.01.0200.tar.gz. Extract this tarball to a directory in your hard drive and open a terminal and cd into that directory. Type this in the terminal window: $ ./configure --with-iodbc --enable-pthreads $ make $ sudo make install Verify that you have the file psqlodbcw.so in the /usr/local/lib directory.

• Connecting Windows 7 to legacy Linux Samba share

  - by bconlon

  I have had to rebuild my Windows 7 PC and all has gone fairly well until I tried to connect to a Samba share on a legacy Linux box running Redhat 8. No matter what combination of domain / user /password I would just see the same message of: "The specified network password is not correct." This is a misleading error, very annoying and a little confusing until I found a hint that Windows 7 default authentication was not supported on older Samba implementations. I guess I figured this out once before as it used to work before the rebuild! Anyway here is the solution: 1. Control Panel->System and Security->Administrative Tools->Local Security Policy (or run secpol.msc). 2. Select Local Policies->Security Options->Network security: LAN Manager authentication level. 3. Select 'Send LM and NTLM - use NTLMv2 session security if negotiated' and click OK. #

• Desktop shortcut to create a new desktop shortcut doesn't do anything

  - by David M. Karr

  It's weird that creating desktop shortcuts is currently so primitive. I found the following: Create Shortcut / launcher on Desktop in Ubuntu 12.04 That helps. However, if there's something wrong with the shortcut, it just doesn't do anything. For instance, I tried to create a shortcut for this command line to create a shortcut. When I double-click it, it just does nothing. This is the resulting text of my "Create Desktop Shortcut.desktop" file on the desktop: [Desktop Entry] Version=1.0 Type=Application Terminal=false Icon[en_CA]=gnome-panel-launcher Exec=/usr/bin/gnome-desktop-item-edit ~/Desktop/ --create-new Name[en_CA]=Create Desktop Shortcut Name=Create Desktop Shortcut Icon=gnome-panel-launcher As I said, when I double-click this, or right-click it and select Open, nothing happens. Is there a log file where something about this would be written to?

• Towards an F# .NET Reflector add-in

  - by CliveT

  When I had the opportunity to spent some time during Red Gate's recent "down tools" week on a project of my choice, the obvious project was an F# add-in for Reflector . To be honest, this was a bit of a misnomer as the amount of time in the designated week for coding was really less than three days, so it was always unlikely that very much progress would be made in such a small amount of time (and that certainly proved to be the case), but I did learn some things from the experiment. Like lots of problems, one useful technique is to take examples, get them to work, and then generalise to get something that works across the board. Unfortunately, I didn't have enough time to do the last stage. The obvious first step is to take a few function definitions, starting with the obvious hello world, moving on to a non-recursive function and finishing with the ubiquitous recursive Fibonacci function. let rec printMessage message  =     printfn  message let foo x  =    (x + 1) let rec fib x  =     if (x >= 2) then (fib (x - 1) + fib (x - 2)) else 1 The major problem in decompiling these simple functions is that Reflector has an in-memory object model that is designed to support object-oriented languages. In particular it has a return statement that allows function bodies to finish early. I used some of the in-built functionality to take the IL and produce an in-memory object model for the language, but then needed to write a transformer to push the return statements to the top of the tree to make it easy to render the code into a functional language. This tree transform works in some scenarios, but not in others where we simply regenerate code that looks more like CPS style. The next thing to get working was library level bindings of values where these values are calculated at runtime. let x = [1 ; 2 ; 3 ; 4] let y = List.map  (fun x -> foo x) x The way that this is translated into a set of classes for the underlying platform means that the code needs to follow references around, from the property exposing the calculated value to the class in which the code for generating the value is embedded. One of the strongest selling points of functional languages is the algebraic datatypes, which allow definitions via standard mathematical-style inductive definitions across the union cases. type Foo =     | Something of int     | Nothing type 'a Foo2 =     | Something2 of 'a     | Nothing2 Such a definition is compiled into a number of classes for the cases of the union, which all inherit from a class representing the type itself. It wasn't too hard to get such a de-compilation happening in the cases I tried. What did I learn from this? Firstly, that there are various bits of functionality inside Reflector that it would be useful for us to allow add-in writers to access. In particular, there are various implementations of the Visitor pattern which implement algorithms such as calculating the number of references for particular variables, and which perform various substitutions which could be more generally useful to add-in writers. I hope to do something about this at some point in the future. Secondly, when you transform a functional language into something that runs on top of an object-based platform, you lose some fidelity in the representation. The F# compiler leaves attributes in place so that tools can tell which classes represent classes from the source program and which are there for purposes of the implementation, allowing the decompiler to regenerate these constructs again. However, decompilation technology is a long way from being able to take unannotated IL and transform it into a program in a different language. For a simple function definition, like Fibonacci, I could write a simple static function and have it come out in F# as the same function, but it would be practically impossible to take a mass of class definitions and have a decompiler translate it automatically into an F# algebraic data type. What have we got out of this? Some data on the feasibility of implementing an F# decompiler inside Reflector, though it's hard at the moment to say how long this would take to do. The work we did is included the 6.5 EAP for Reflector that you can get from the EAP forum. All things considered though, it was a useful way to gain more familiarity with the process of writing an add-in and understand difficulties other add-in authors might experience.

• Can't ping Ubuntu laptop from my LAN

  - by oskar

  My laptop has Ubuntu 10.10 and is connected to my router with full internet access, yet I can't ping it from other computers on my LAN. I tried the following: I can successfully ping those other computers from my Ubuntu laptop, so I didn't accidentally connect to someone else's network. I can successfully ping my Ubuntu laptop from itself, though I don't know if that means anything. I haven't messed with iptables at all, so it currently doesn't have any rules set that would cause it to reject anything. I made a DHCP reservation for my laptop's MAC address in my router to make sure I was always using the correct IP address. Please note that I am using a "command line only" install of Ubuntu, so I can't use any GUI network config tools. The reason I want to ping it is because I am trying to run an NFS server on the laptop, yet despite correctly setting it up I cannot access the NFS volume on another computer because it isn't even visible on the network right now.

  Access an encrypted home directory when you’re not logged in – say, from a live CD – and all you’ll see is a README file. You’ll need a terminal command to recover your encrypted files. You should also back up your mount passphrase ahead of time – you may need this in the future. While eCryptfs normally decrypts your files with your login passphrase, the mount passphrase may be necessary if eCryptfs’s files become lost.

• Black Screen on boot on a Lenovo IdeaPad Z575

  - by Davis

  So I tried to install Wubi. On boot, when I select Ubuntu it starts then I get a purple screen then black screen. My monitor is like completely off. So then I have to hold down my power button and shut it off. I boot it up then held shift and typed in "nomodeset" after the second to last line, but then when it boot it went into the command prompt thing and just stopped after "checking battery" or something. This is my first time installing any linux distro. I want to install it alongside windows and dual boot it with wubi because that is easy and simple. This is the laptop I have: http://www.newegg.com/Product/Product.aspx?Item=N82E16834246328

• How do I set up FTP on localhost?

  - by EmmyS

  On my old machine (back on Lucid!) I used XAMPP for local dev work. XAMPP installed everything for you, including setting up FTP to your localhost (/var/www) directory, since permissions don't allow you to write directly to it. I have a new machine running Precise, and decided to do things the grown-up way. I installed everything using tasksel, and got apache, php, mysql, and phpmyadmin up and running. But it's kind of a pain to have to create and edit all my files via gksudo gedit on the command line, and sooner or later I'm going to have to upload images. How can I set up FTP so that I can "upload" files to my localhost server?

• Unsatisfied Link Error and missing .so files when starting Eclipse

  - by Keidax

  I upgraded to the 12.04 beta yesterday. Now, when I try to start Eclipse, I get the splash screen and then this error message: An error has occurred. See the log file /home/gabriel/.eclipse/org.eclipse.platform_3.7.0_155965261/configuration/1335382319394.log . The log file says something like this: java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons: no swt-gtk-3740 in java.library.path no swt-gtk in java.library.path Can't load library: /home/gabriel/.swt/lib/linux/x86_64/libswt-gtk-3740.so Can't load library: /home/gabriel/.swt/lib/linux/x86_64/libswt-gtk.so followed by many more error messages. The /home/gabriel/.swt/lib/linux/x86_64/ directory exists, but is empty. I also tried reinstalling eclipse with no success. Any ideas?

• Ubuntu 12.04 doesn't start after installing with LiveUSB

  - by Kevin Arutyunyan

  I need help! I installed Ubuntu with my LiveUSB, and it said restart to use your system, so I restarted. Now I am just stuck in a completely black screen with a blinking _ I'm already waiting 10 minutes for something to happen, but there's nothing. I don't know what the problem could be, but maybe the message I got during installation that said 'APT couldn't be configured, so no additional apps will be installed' was the problem? I'm still waiting.. Fast answers please :) thanks.

• Patch an Existing NK.BIN

  - by Kate Moss' Open Space

  As you know, we can use MAKEIMG.EXE tool to create OS Image file, NK.BIN, or ROMIMAGE.EXE with a BIB for more accurate. But what if the image file is already created but need to be patched or you want to extract a file from NK.BIN? The Platform Builder provide many useful command line utilities, and today I am going to introduce one, BINMOD.EXE. http://msdn.microsoft.com/en-us/library/ee504622.aspx is the official page for BINMOD tool. As the page says, The BinMod Tool (binmod.exe) extracts files from a run-time image, and replaces files in a run-time image and its usage binmod [-i imagename] [-r replacement_filename.ext | -e extraction_filename.ext] This is a simple tool and is easy to use, if we want to extract a file from nk.bin, just type binmod –i nk.bin –e filename.ext And that's it! Or use can try -r command to replace a file inside NK.BIN. The small tool is good but there is a limitation; due to the files in MODULES section are fixed up during ROMIMAGE so the original file format is not preserved, therefore extract or replace file in MODULE section will be impossible. So just like this small tool, this post supposed to be end here, right? Nah... It is not that easy. Just try the above example, and you will find, the tool is not work! Double check the file is in FILES section and the NK.BIN is good, but it just quits. Before you throw away this useless toy, we can try to fix it! Yes, the source of this tool is available in your CE6, private\winceos\COREOS\nk\tools\romimage\binmod. As it is a tool run in your Windows so you need to Windows SDK or Visual Studio to build the code. (I am going to save you some time by skipping the detail as building a desktop console mode program is fairly trivial) The cbinmod.cpp is the core logic for this program and follow up the error message we got, it looks like the following code is suspected.   //   // Extra sanity check...   //   if((DWORD)(HIWORD(pTOCLoc->dllfirst) << 16) <= pTOCLoc->dlllast &&       (DWORD)(LOWORD(pTOCLoc->dllfirst) << 16) <= pTOCLoc->dlllast)   {     dprintf("Found pTOC  = 0x%08x\n", (DWORD)dwpTOC);     fFoundIt = true;     break;   }    else    {     dprintf("NOTICE! Record %d looked like a TOC except DLL first = 0x%08X, and DLL last = 0x%08X\r\n", i, pTOCLoc->dllfirst, pTOCLoc->dlllast);   } The logic checks if dllfirst <= dlllast but look closer, the code only separated the high/low WORD from dllfirst but does not apply the same to dlllast, is that on purpose or a bug? While the TOC is created by ROMIMAGE.EXE, so let's move to ROMIMAGE. In private\winceos\coreos\nk\tools\romimage\romimage\bin.cpp    Module::s_romhdr.dllfirst  = (HIWORD(xip_mem->dll_data_bottom) << 16) | HIWORD(xip_mem->kernel_dll_bottom);   Module::s_romhdr.dlllast   = (HIWORD(xip_mem->dll_data_top) << 16)    | HIWORD(xip_mem->kernel_dll_top); It is clear now, the high word of dll first is the upper 16 bits of XIP DLL bottom and the low word is the upper 16 bits of kernel dll bottom; also, the high word of dll last is the upper 16 bits of XIP DLL top and the low word is the upper 16 bits of kernel dll top. Obviously, the correct statement should be if((DWORD)(HIWORD(pTOCLoc->dllfirst) << 16) <= (DWORD)(HIWORD(pTOCLoc->dlllast) << 16) &&    (DWORD)(LOWORD(pTOCLoc->dllfirst) << 16) <= (DWORD)(LOWORD(pTOCLoc->dlllast) << 16)) So update the code like this should fix this issue or just like the comment, it is an extra sanity check, you can just get rid of it, either way can make the code moving forward and everything worked as advertised.  "Extracting out copies of files from the nk.bin... replacing files... etc." Since the NK.BIN can be compressed, so the BinMod needs the compress.dll to decompress the data, the DLL can be found in C:\program files\microsoft platform builder\6.00\cepb\idevs\imgutils.

• Change language encoding for file uploading

  - by jc.yin

  Previously we were running a Wordpress site on a Mac OS Server machine. We had several hundred images with Chinese characters for the image names. Now we're trying to migrate to a Ubuntu system and everything is fine except the images. Every time I try to upload an image with a Chinese name via FTP, I get the following message: "MyImage contains illegal characters. Please choose an appropriate text encoding" I have no idea how to solve this issue, do I need to somehow change the system language encoding in Ubuntu to allow for image uploading? Thanks
